PORTABLE BREASTWORK.

Application filed March 19, 1915.

To all whom it may concern:

Be it known that I, RAY V. DAVIS, a citizen of the United States, residing at Brownsville, in the county of Fayette and State of Pennsylvania, have invented new and useful Improvements in Portable Breastworks, of which the following is a specification.

The invention relates to breastwork, and more particularly to the class of portable breastwork.

The primary object of the invention is the provision of a structure of'this character wherein the same can be placed at any desired point for protection against enemies while in conflict with warring nations, the structure being of novel form so that it may be quickly erected and adjusted for defense in deflecting the enemys bullets or gun shots, yet rifle and gun fire may be had from behind the structure without exposure to the fire of the rifles or guns of the enemy.

Another object of the invention is the provision of a structure of this character wherein it is made up of a plurality of sections separable from each other so that the structure can be brought into compact form for the easy transportation thereof from one point to another, thereby rendering it readily portable.

A further object of the invention is the provision of a structure of this character which is simple in construction, reliable and eflicient in use, strong, durable, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings :Figure 1 is a perspective view of the breastwork constructed in accordance with the invention. Fig. 2 is a vertical transverse sectional view therethrough. Fig. 3 is a fragmentary vertical sectional view through one of the adjustable props. Fig. 4 is a perspective view of one of the legs or supports for the breastwork. Fig. 5 is a fragmentary perspective view of one of the plate sections of the breastwork. Fig. 6 is a fragmentary perspective View of the companion section. Fig. 7 is a perspective view of one of the anchoring pins or stakes.

responding parts throughout the several views in the drawings.

Referring to the drawings in detail, the breastwork comprises a plurality of sheet metal sections 10 of any desired number for the extending of the breastwork throughout a predetermined area. One end of each section is formed with an offset portion 11 provided with spaced slots 12 in the shoulder 13 at right angles to the said section formed by the portion 11, while the other end of the section is provided with hook-like ears 14 so that on the joining of the sections in a row the same can be detachably connected together by the engagement of the ears 14 in the slots 12, one end of each section being designed to abut the shoulder 13 on a section adjacent thereto, and when the said sections are joined the outer surfaces thereof are flush with each other.

On the inner face of each section 10 near one lower corner thereof is riveted or otherwise fixed a bearing 15 to which is swingingly connected a channeled leg or support 16 which is connected to the said bearing 15 through the medium of a pivot 17 so that the section 10 can be angularly adjusted relative to the surface of the ground on which the leg or support 16 rests, the leg or support being provided at its free end with a loop 18 which is formed from a metallic strap, and through this loop is passed an anchoring pin or stake 19 which is driven into the ground for the fastening of the leg or support thereto. The pin or stake 19 has mounted therein a stop 20 which is adapted to engage the loop 18 to limit the driving of the pin or stake in the ground.

Mounted on the outer face of each section near the opposite lower corner thereof is a bearing 21 in which is pivoted a loop 22, and through which is passed another of the pins or stakes 19, and in this manner the breastworks are securely fastened to the ground. Riveted or otherwise secured to the inner face of each section 10 near one upper corner thereof is a bearing 23 in which is pivoted an adjustable prop comprising the stem section 24 and the sleeve section 25 which telescopes over the stem section and is provided with an elongated slot 26 longitudinally therein, and laterally extending notches 27 communicating with the said slot, while fixed in the stem section 24 is a pin or lug 28 which is slidable in the slot 26 to engage in any one of the notches 27 for the locking of the prop in adjusted position to sustain the section 10 raised or lowered as the 0ccasion may require.

Formed on the sleeve section 26 is a reduced squared solid end 29 which is adapted to detachably fit in a socket 30 formed by the cross straps 81 which are arranged in spaced relation to each other in the channels of the legs and are riveted thereto, the squared end 29 being detachably fastened in the said socket 30 through the medium of the pin 32 which is passed through the side portions of the leg and also through the end 29 of the prop.

Formed in each section 10 in rows are spaced openings 33 which are adapted to be closed by swinging shutters 34 pivoted at- 35, each shutter being provided on its inner face with a hand knob 36 so that the same can be manipulated for the opening and closing thereof from the rear of the breastwork. These openings 33 in the sections 10 serve as peep holes or firing open ings for rifles or guns. It will be apparent that the breastwork can be used with disappearing guns or for firing rifles or other weapons.

From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of use of the device will be clearly understood, and therefore a more extended explanation has been omitted.

It is of course to be understood that changes, variations and modifications may be made in the invention herein described. and disclosed in the accompanying drawing, such as come within the scope of the appended claims without departing from the spirit of the invention or sacrificing any of its advantages. Furthermore, the parts of the structure can be made from any desi.r-' able material.

hat is claimed is:

1. In portable breastworks, a plurality of plate sections, means for detachably inter locking the sections to each other, supports swingingly connected to each plate section, means for angularlv adjusting the plate sections relative to the supports and also sustaining the same in such adjusted position, the said plate sections being provided with a plurality of openings, shutters swingingly connected to the sections for closing the said openings, loops fixed to the supports and the said sections, and anchoring means passed through the loops for securing the plates and supports to the ground.

2. In portable breastworks, a plurality of plate-like sections, means detachably connecting the sections together, supports swingingly connected to the respective sections, a stem swingingly connected to each section, a sleeve detachably connected to each support and having a slot provided at intervals with offset notches, the said stems being slidably telescoped within the sleeves, and pins fixed in the stems and working in the slots for engagement in any one of the notches to adjustably secure the plate sections in angular position.

3. In portable breastworks, a plurality of plate-like sections, means detachably connecting the sections together, supports s'winging'ly connected to the respective sections, a stem swingingly connected to each section, a sleeve detachably connected to each support and having a slot provided at interval with offset notches, the said stems being slidably telescoped within the sleeves, pins fixed in the stems and working in the slots for engagement in any one of the notches to adjustably secure the plate sec tions in angular position, and means for anchoring the plate sections and supports to the ground.

4. In portable breastworks, a plurality of plate-like sections, means detachably connecting the sections together, supports swingingly connected to the respective sections. a stem swingingly connected to each section, a sleeve detachably connected to each support and having a slot provided at intervals with offset notches, the said stems being slidably telescoped within the sleeves, pins fixed in the stems and working in the slots for engagement in any one of the notches to adjustably secure the plate sec tions in angular position, means for anchoring the plate sections and supports to the ground, the said plate sections being provided with a plurality of openings, and shutters carried by the sections for opening and closing said openings.

In testimony whereof I aflix my signature in presence of two witnesses.

I RAY IV. DAVIS.
